Welcome to Petroleum Geology Forums

Difference between current biotoc and abiotic theory of oil formation and me;
regarding abiotic theory people they have sufficient evidence that oil has been generating deep the earth origin and migarting toward crust of earth. it is an ongoing process under the mantle of earth but they have ignored the chemical evidence (very clear and strong evidence ) of biotic origin of oil.we can not ignore it any how. so it conclude us oil is coming from deep origin of earth but biotic in origin without the involvement of fossils of past marine life.
2) according to biotic theory people ,we are getting oil where the fossils of past marine life are buried . most of driller are using this method and we can not this practical and well tested experience . i agree that oil should be there where sediments of this organic material but there is without involvement of fossils my experiments also shows it oil should be there near organic sediments but without any role of fossils.so crude oil is biotic in origin but not a fossil fuel.it also sound us that earth itself is a living organism and producing oil like a bark oil supported by another visual and intelligent evidences.

Suresh,
If I understand you right, You think that thermal generation of oil and gas from organic ("fossil") material is not the main process, but that substantial, if not all oil is abiotic?
You are probably aware of the theory of Professor Gold, astrophycisist, who defended this theory, originally put forward by russian geologists.
Typically, the abiotic theory is suggested and defended by people who are quite ignorant of petroleum geology or especially geochemistry. My research, and that of others has shown that there is a very significant correlation between amounts of oil found and the amounts that were generated thermally from identified source rocks. The latter normally are effective when organic carbon content reaches 1.5% or more. Also the fingerprinting by a multitude of geochemical compounds, and isotope analysis tells us that the thermal generation from organic remains is paramount.
Please note that remarkably little oil has been found in basement areas which are drilled nevertheless for minerals. However, somewhat confusing, oil can migrate into wheathered basement, like arkose, thereby suggesting the oil was generated from igneous rocks.
A significant example where the source can be identified easy is the "ichtyol" oil, with fish scales in it, and the fossil fish shales that form the corresponding sourcerock.
